I have the usb duemilanove and currently connect it to the computer. Since there's no on/off switch, I find myself having to unplug the usb cable to remove power from the arduino to make adjustments on the breadboard. I'm afraid of wearing out the usb connection. Anyone have any tips?

best way to turn off power

Does that board have a diode to protect the USB port from power applied to the board? If so, could you remove it and install a switch there?
